Roster36 is a web directory, a public record of active websites catalogued under twenty-two subject headings. The directory was assembled to give browsers a clear, organised starting point for exploring what is online across a broad range of subjects. The structure of Roster36 follows a simple editorial principle: sites are filed under the heading that best reflects their primary subject. Where a site spans multiple fields, it is entered under the most appropriate single section. The goal is clarity of record, not exhaustive taxonomy. Every entry in the register has been reviewed before approval. The directory is not an automated index but a curated file, which means each site you encounter in Roster36 has been assessed against basic criteria for quality and relevance. The register currently holds 827 entries across twenty-two sections. Those figures are updated as new submissions are reviewed and approved. The directory accepts submissions from any site that meets the criteria; approval is not guaranteed, but the process is straightforward. Roster36 is free to browse and free to submit. There is no charge for inclusion, and no premium placement for payment. The register is maintained with the same rules applied to every entry, regardless of the submitter.
